An accelerometer is hardware that measures the acceleration of a device. It's the component that allows you to control apps and games by moving your device through space.

I've been experimenting with this and I tried three different methods for controls...

The first method moves an object using Translate, as shown in the Unity documentation. For the second test, I modified a free-floating camera script, so the player can fly the camera around the scene. Lastly, I modified my vehicle/hover controls (shown in the image above), which is my favorite and the most fun.

I've never liked these kind of "motion controls" because there is too much latency. I've only played one or two games that used the technology effectively. They worked around the low latency issues by creating a game that was slow and relaxing in-nature.

My device doesn't have a gyroscope so I'm not able to test those features.

So, I've learned a few things... 1) I have a few different options for controlling the player via the accelerometer. 2) Due to the latency, its best to create a game that doesn't require fast reactions or precise movement. 3) I am not able to use the gyroscope class.
